I've been working on this all day, and I'm at my wits' end. I'm using the Twitter Bootstrap with the latest version of jQuery; I have a series of anchor tags that are supposed to pass several data points to create a dynamically generated HTML5 video player in a modal window. Here's the HTML:

As you can see, I'm trying to pass different versions of the same video to a JavaScript function that will test for supported video formats in the browser, create a new Video element, then attach the appropriate file name as the .src attribute of the Video element. However, when I write the jQuery .data() elements to the console, they all come back undefined!
